The redwood tree was hand-painted using Fractal Design Painter 2.0 and a Wacom
pressure sensitive tablet. The tree was roughed out using a Sharp Pencil
brush. Catchlights and bark details were drawn using the Single Pixel
The 3D Stanford "S" was modeled using SoftImage's Creative Environment
v2.6.1. The scene was lit using two lights, one of which was a strong
spotlight partially masked by a matte created from the painting of the
redwood tree. The scene was then rendered with ray-traced shadows
and antialiased using a Bartlett filter.
The blue background was created using Painter. The spotlight was added using
the Apply Lighting effect. This is strictly a 2D effect.
The redwood tree, the rendered "S", and the blue background were composited
together using Adobe Photoshop 2.0. The Magic Wand and Lasso tools were used
to define antialiased mattes to control the compositing. Dark fringes were
added around the "S" to heighten its readability, and the composite image was
sharpened slightly to enhance details.
The frame and titling were generated using Painter. The background was created
using the Apply Surface Texture effect. The letters were drawn, lit, and
shadowed using the Fill, Apply Lighting, and Soften Focus effects, each masked
by friskets created from the letters themselves. The entire frame was then lit
again to simulate billboard lighting, and the composite Stanford logo was
